Story
Based on CrowPanel Advance 2.8" or 3.5", and EnSens Add-on.
This project turns your Elecrow CrowPanel Advance into a smart indoor air quality station. By plugging in the EnSens Add-on module (sold separately), you enable precise real-time monitoring of your indoor environment.
The EnSens Add-on integrates Bosch’s high-precision BME688 sensor and connects directly to the panel through a dedicated interface. It measures:
- Temperature
- Humidity
- Barometric Pressure
- Air Quality Index (IAQ)
- CO₂ Equivalent (eCO₂)
- Volatile Organic Compounds (VOCs)
The dedicated application for CrowPanel displays:
- CurrentTemperature, Humidity, and Pressure – along with arrow indicators showing the speed and direction of change.
- IAQ (Indoor Air Quality Index) – a composite measure of air quality, with a side color scale indicating whether the air is clean, acceptable, polluted, or hazardous.
- CO₂ and VOC Levels – two key factors affecting comfort and health. These values are shown with color-coded indicators to highlight potentially dangerous levels.
- Settings Menu – allows switching between Celsius/Fahrenheit and mmHg/hPa units.
The application is available open-source on GitHub: 👉 github.com/Grovety/CrowPanel_MiniMeteo
You can either:
- Use prebuilt firmware for your screen size (2.8” or 3.5”), or
- Modify the open-source code to tailor the app to your own needs.
Installation takes less than 2 minutes:Just download the firmware archive for your panel, unpack it, and run the included installer. It will automatically detect your panel and flash it with the ready-to-use MiniMeteo application.
